Abstract

The process for generating at least one warning signal relating to the level in a tank (3) for storing a product (4) comprises the following steps: - the storage level of the product in the tank, together with the values of the product quantity consumed during predefined time intervals are determined, - these values are placed in memory together with the associated measurement instants, - at other successive instants the values placed in memory of the product quantity consumed are used to calculate a value of the estimated quantity of product which will be consumed in the future, this estimated value is subtracted from the last measurement value so as to obtain an estimated value of the storage level at a future instant, this estimated value of the storage level is compared with a preset threshold, and a warning signal is generated if the estimated value is less than the preset threshold.
